I am using the Robotiq 2 finger adaptive gripper 85. I have the latest version of the URCap installed with a UR5. The robot, at random times, will completely stop what it is doing and be in a dormant state. The light on the grippers turns red and blue and it will not grip. As far as the robot goes, it seems like it is waiting for the grippers to grip but they won’t. There are no popups on the pendant until I try to reactivate the grippers, and then I get an error message that says “An error occurred with the grippers. Go to installation tab > Gripper and tap ‘Scan’. Error code: [UCG-1]”. We haven’t ever really gotten this before (the robot has been running for almost 2 years now without this problem), so I’m not sure what the actual issue is, but it has shut down production twice now. Any help would be appreciated.

Hello @Mschack, I opened a support ticket to assist you with this issue. You should receive an email shortly.

I have the same kind of issue here. 2-finger Adaptive Gripper 85 connected to a wrist camera. When using the gripper, at random times, the robot stops and the LED flashes in red and blue color. The LED on the wrist camera connection also changes color.
Can I get some help with that? Thanks

Hi @David_Levasseur, Same is happening to me! My 2F-85 gripper that I have been working with it fine for about a year all of a sudden stops and starts blinking red blue light. I'm using a UR5e. I also do not have the USB converter cable to run RUI. What should I do?

Hi @ijenab, I opened a support ticket for you. You should receive an email about this shortly.

hello I have the same problem on 2 cobot. 1 UR5 CB polyscope v3.13 + sensor FT300 + gripper 2F-140 old model with gripper urcaps 1.8.1 and another cell with UR5 CB polyscope v3.13 + sensor FT300 + gripper 2F-140 new generation robotiq gripper with urcaps 1.8.1. The light goes red then blue immediately, no error message on the pendant unless the LED stays red longer the message window opens with a pinch communication. Without message I select just pause and play to continue the cycle.  I have the same cell latest generation gripper with UR5 eSeries and no problem. Do you have a solution?

hello!! I'm facing the same issue too, my gripper toolbar would ask me to scan for my gripper and that's it. 

Did you ever find a solution on this? I have the same problem with a UR3 and the 2F 140 grippers sometimes it works and it can suddenly just stop working for no reason. Maybe @David_Levasseur can help me? 

Hi @GustavCejnAB,

There are some reasons that could explain this issue, including outdated software or even hardware failure. I have opened a support ticket to contact you directly and gather information to advise accordingly.

I encountered the similar issue while using 2F-85 gripper with ur5e.
When the gripper is sometimes switched on, the blue and red light will both turn on; as a result, the gripper does not function, and restarting it does not make it work either!
